Hello everyone,
I've got in inground hot tub (probably built in the 80's or 90's. Anyway, the filter housing is old and beat up, as well the heater died so I'm looking to refresh/clean up the pump/filter/heater plumbing as part of this project. I have a few questions,
1. All the lines are ridged 2 inch, however the current set up reduces the 2 inch out of the pump, down to 1.5 for the filter, then back up to 2 inch for the return. Is this normal? Should I replace the filter & housing with one that accepts 2 inch lines, or is there something about filters that need the higher velocity that would come with 1.5 inch?
2. I know in pools, extra effort to eliminate a couple of 90 degree elbows isn't normally worth it, but in a spa, I'm wondering if this is a more useful venture. I figure I can eliminate two, or three 90's but repositioning things. In one section I could eliminate three if I use flex pipe. I know flex pipe has higher resistance, but I'm guessing this would be offset by the removal of three elbows? I live in a climate with no termites, or extreme cold, so I'm not worried about the flex pipe failing.
Thanks very much in advance,
Chris
